Croname, Incorporated, qhicagfoplll., a corpo;

ration of Illinois Application September 28, 1945","Serial No. 3. Claims. (Cl. 24S-.7201) Theinvention here disclosed relates to.. the

mountingof glass scales, such as used in radio.

receiving sets.

These scales, to properly serve their purpose., must beaccurately positioned. The problem has been to mount the glass inthe required position but without strain and` so that distortions and shocks. will not break orcrack the same. n

Objects of` this invention have been to provide a mountingwhich would hold lthe glass vaccurately. in position .without imposinganystrains ovrl'theV sameand which, would be of simple and inegipensiveconstruction, easilyassembled and other.- wise practical and generally desirable.l

Other objects and the novelfeatures by which. the purposes of the. invention are attainedare.

set. forth or will-appear inthe course of the following. kspecication The drawing accompanying and forming part of the specification.illustrates a present practical embodiment of the invention. Structure, how:V

ever, maybe modied andchanged as regardsthisI present illustration, all within the trueintent.

and broadscope of theinvention las hereinafter dened and claimed.

Fig.. 1 in the drawing is a front elevation Ofl a radio scale incorporating featuresof the inf. vention;

Fig. 2 is an enlarged end elevationof thesame in relation to the enclosing cabinet;

Fig. 3,is a further enlarged broken sectional detail on substantially the plane of line` 3.-3;,of

Fig'. 1;

Figs. 4 and 5 are broken and .sectional details of a modification; and

Fig. 6 is a broken sectional detail of another modification.

In Figs. 1 and 2, the. glass scale or so-.called crystal of a radio receiver is indicated at,5,

supported in spaced relation in front of thesup-V porting plate. or framed. Thev latter is usually mounted by means of some kind of -a bracketl on the chassis of the receiver .so thatv the scale will occupy a predetermined-relation'.to the chas: sis andfh'enc'el to. the escutcheon of the cabinet when the chassisismounted in its proper relation in the cabinet.'

In Fia the fenffwellfofaabinet- Strutture is indicated at 8, with an escutchefon Vset therein, the glass scale appearing in back` of this escutcheon.

Theglass is exibly supportedin self-centering relation by. a series oi spring clipsof U forma,.- tion, in the natureof hairpinsprings, designated I0. These are shown, as made up of flat-,strip stock andas tting in, rectangular holesvl'l. in thesupporting plate 6.. and thus heldA` against twisting or turning.

These clips, further, are of special design in that they are doubled in Wedge-like formation providing relatively inclinedsides Ill; I3, adapted.`

to be readily pushed` through the openings Il; and Awith one-.sidehaving a hooked terminall I4 to engage over `one edge of. the opening andfthe othery side I311onger, and; having. one indentation ltohook over theopposite edge and-a second;

indentation I6 toward; the. end. and .adaptedl to.

forma seat fortheiedge ofthe glass..

Inusethelclips arejust pushed through, the

openings. H', and they may bey pushed through..

from either side, and then theglass is. seated:

in the notches.. or Yindentations I6, in. the free ends o'f theY clips, theseends being free enoughA to'be sprung sufliciently toengage the edge. of;

the glass.

The vnumber.andsdisposition of the clips mayA vary 'accordingto the sizeand shape oftheglass.- For an ordinary size scale the clips may be posi,-y tioned as indicatedinl'ig 1-, two at the top near the ends, two at the, ends` and. one. at the .bottom near the center. This.arrangementcenters and holds a' rectangular paneljsuch asrillustrated, al-A lowing for small'imperfections in the glass, and. holding it Yyieldingly though rmly, accurately positioned in respect;A to the rest.` of` the mech-f anism.

As shown,V particularly in. Fig. 2, the longervv spring extensions of. the clipsl support the scalev spaced in front of the frame or IrmuntingV plate. (-withl roomfor thepointer or indicating element L11 to operateinbetween the frame and theglass andwith clear, spaceE substantially allabcut the; glassfor iavorableedge lighting or .other illu,-v minating effects. These clips may be spacedbacklor away from .theedgespf the escutcheonpening so. as. not to be visible, and thefescutcheonmay bemade with aliinwardly extending. flange,

suchas indicatedat I Bf, tofurther assist-inconcealing the mounting clips.

"1n theseviews the indtedldl portion IB for setting and holding the edge of the dial is split, as indicated at 20, providing separate tongues 2|, 22, and one of these tongues, 2|, in the illustration, is bent inward, as in Fig.

5, to engage over the end of the dial while the Fig. 4 shows the upper left hand corner of the glass. At the upper right hand corner a clip Will be used having the tongue 22 bent downto engage the end of the glass and the tongue 2| left in its original state to engage over the upper edge of the glass. In this Way `the glass may be located endwise by just two upper, corner vholding clips, and a single clip be used at the bottom positioned to engage the mid-length portion of the lower edge. Thus only three clips may suilice in place Vof ve'clips such as 'shown in Fig. 1.

Fig. 6 illustratesV a second modification in which theY long arm of the clip carrying the seat for the glass is disposed at the far side of the clip receiving opening Il so that pressure of the glass against the free end of the clip tends to expand the clip and hold it more securely in the seatingopening in the supporting'frame. This construction allows for a larger size glass on a givenv size frame.V

While generally preferred to make the clips of iiat 'strip material, itis contemplated that they may bemade of round wire, doubled to provide the same laterally extended holding effect for engagement in the rectangular openings ll and for gripping engagement with the edges of the glas's.""""

The new method of mounting heredisclosed provides a maximum 'of open space about the edgesof the glass for edge illumination and other features.` Thecushioning eiect provided by the clips is'present in' both the direction in the plane of'or parallel with theglass Vas 'well as Vat right anglesto such a plane. The holding portion of the clip can move back and forth or in and out with respect to -the frame and also up and down, providing the effect'of universal self-adjustment and cushioning. y f

' In allrforms of the invention disclosed a certain Vamount of fulcrum adjustment is provided and `'allowed for, Figs. 5 and illustratin'g'two of the diierent ways in which this may be accomplished.

While usually of glass and for that reason ordinarily referred toAby that name, it will be understood that the invention is applicable to dials and scales generally, whether made of glass, plastic or other materials, and the claims are to be construed accordingly.

What is claimed is: v Y

1. An instrument scale, a support therefor, and reversely bent spring clips'having doubled side portions yieldingly engaged with the support and single side portions 'projecting from the support and yieldingly engaged with the scale, said scaleV having angular corners and said clips being constructed of iiat strip material and said projecting side portions of the same having split ends disposed to engage over angularly related corner edgesof the scale, 'y

2, Means for accurately mounting a glass scale for a radio receiving s et in yieldingly held cushioned relation comprising a Ysupporting plate having openings therethrough disposed in the approximate outline of the scale to be mounted, substantially `ll-shaped spring clips extending through said openings and having indentations in the opposite sides of the same engaged over opposite edgev portions of the openings to yieldingly position and retain the clips in said openings, said clips having free extending arm portions projecting away from the face of the support and provided with indentations spaced all A approximately the same substantially equal distance away frornthe face of the support and collectively disposed in an outline generally corresponding to but of less external dimensions than the outline of the scale to be mounted and a glass scale of slightly greater outline dimensions than the outline formed by said indentations in the free projecting arms of the clips, said scale having its edge seated in said spring arm indentations andthereby spreading said spring arms suiciently to effect firm yielding grip of the scale and the support of the latter in accurately ioned relation comprising a supporting plate having openings therethrough disposed in the approximate outline of the scale to be mounted, substantially U-shaped spring clips extending through said openings and having indentations in the opposite sides of the same engaged over opposite edge portions of the openings to yieldingly position and retain the clips in said openings, said clips having free extending arm portions projecting away from the face of the support and provided with indentations spaced all approximately the same substantially equal distance away from the iace of the support and collectively disposed vin an outline generally corresponding to but of less external dimensions than the outline of the scale to be mounted and a glass scale of slightly greater outline dimensions than the outline formed by said indentations in the free projecting arms of the clips, said scale having its edge seated in said spring armV indentations and thereby spreading said spring arms sufficiently to effect firm yielding grip of the scale and the support of the latter in accurately placed location spaced substantially parallel away from the face of the supporting plate, said openings in the supporting plate having opposite edges substantially parallel to the edges of the glass scale and the clips being formed of iiat strip material and disposed with the flat extent of the same in flat bearing engagement with said opposite substantially parallel edges of the openings and thereby held against turning in the openings and with flat extending portions of the spring arms in fiat engagement with the edges of the scale.
